In Windows, the standby and sleep modes have been added for a long time, while in Windows Vista, the sleep mode has been added, however, many people are still used to shutting down a computer when it is not used. In fact, making full use of these models not only saves power consumption, but also restores the system to normal operation as short as possible.
The three modes are defined as follows:Standby

Note: Some browser driver addresses require scientific Internet access.
Set browser driver
Setting the browser address is very simple. You can manually create a directory to store the browser driver, such as C: \ driver, and drop the downloaded browser driver files (such as chromedriver and geckodriver) to this directory.
My computer-> properties-> system settings-> advanced-> environment variables-> system variables-> Path, add the "C: \ driver" directory to the Path value.

The effect of sleep is needless to say, almost every language provides a similar function, the call is very simple. The function of sleep is to let the program wait for some time, and in order to achieve this goal, there are many ways, the simplest is often the most brutal, we will use the following code to illustrate (note: This article refers to the program compiled running environment for Linux)

Recently, for Linux development on arm, C Programs Written in windows need to be transplanted to Linux. The underlying SPI driver implementation and socket communication on the upper layer need to be rewritten, the application also needs to be changed. It does not take much effort to make the program run smoothly throughout the process. Thanks to the powerful eclipse + arm-Linux-GCC combination, however, many interesting problems are found during debugging. One of them is about the differences b
